' CHECK PROTECTOR.

Application led Novemberl, 1921. Serial No. 516,715.

, shall be of improved construction, efficient and convenient to operateand simple and economical in manufacture.

The invention is exemplified in thecombination and arrangement of partsshown in the accompanying drawings and described in the followingspecification and it is more particularly pointed out in the appendedclaims. n

ln the drawings,

Fig. 1 is a vertical sectional View through a check protector', showingone embodiment of the present invention.

Fig. 2 is a view similar to Fig. il, with the parts ina differentposition from that of Fig. 1. l

Fig. 3 is a top plan view of the check protector with parts omitted.

Fig. 4 is a front elevation of the carriage mechanism.

Fig. 5 is a detail showing the escapement mechanism of the carriage.

Fig. (3 is a fragmentary section on line 6-(3 of Fig. 3.

The present invention provides a check protector in which a check isinserted in a frame in which the face of the check is visible and whichis provided with a spring clamp which sei-rates the paper upon which.the payces naine is written. The amount of the check is cut iiito thepaper and at the same time the iihers where the paper is partially cutare saturated with ink, making erasure impossible without -destroyingthe docunient. 'lhe iniprc -sion of the amount upon the check is prodi.ed hy simply striking the different number n a keyboard corresponding tothe figures of the amount of thc check. The keyboard .is also providedwith anynecessary words such as Iay,7 1)01." and Cts.

'lhe device comprises a sheet inctal casing 1() mounted on a hase 11,and having a transverse lstationary shaft 12, upon which key levers 13are mounted in spaced relation to one another for pivotal movement aboutthe shaft. Each -key lever isprovided with a downwardly extending arm14, having a contact foot 15. Springs 16 are attached to the arms 14 andretain the key levers l13 in their uppermost position against a. fixedshaft 1?' extending transversely of the frame 10. livotally mounted onthe shaft 12 is a pair of arms 18, which support a universal har 15)disposed in the path. of the contact vt'eet'l on the key levers. It willbe seen from Fig. 1 that the feet 15 areof different lengths so as topermit different amounts of movement ofthe key levers prior to engagement of the feet with the universal har 19. 'lhe amount-of suchpreliminary movement proportional to the numbers which the differentkeys represent.

Pivotally mounted on a shaft 2() which extends transversely of themachine and is supported by the side Walls of the frame 10,

niI

isa frame 21 having side walls 22 and23.

A spring 24 is attached to an extension 25 formed on the side Wall 22for retaining the frame 2li/in its forward position against the` shaft17, as shown in Fig. 1. Pivotally mounted on the shaft 20 adjacent theinner face of the side wall 22 is an upright bar 26, having a racksegment 27 at its upper end. The segment 27 meshes with a. pinion .28

pivoted at 29 on the side-plate 22 of the frame 21. `Fixed to the pinion28 is a gear 30, which meshes with a pinion 31, rigidly tixed'to a typewheel 32 joui-nailed on a shaft 33 carried by a lateral extension 54 onthe side plate 22. The type wheel 32 carries on its periphery the`various characters I-ii which are used in stamping the check or otherdocument. When the segment 27 is moved forwardly relative to the frame21, the type wheel 32 will be rotated upon its pivot through the chainof gearing described to bring the different characters into printing`line. The bar 26, which carries the segment 27, is provided near thepivot 2() with a gcarlsegineiit 211', which meshes with teeth 37 on theend of an arm 25.', pivotally mounted on the shaft l2. llxtendingthrough the arm .3S is an upper universal ro'd 'or bar 259, which issupported at its ends by. arms 40, also pivoted oni/thc shaft l2. 'lheuniversal rod 39 is held. in ils uppermost position by springs. 4-1secured to the side walls of the frame l() and to the 'Qpposie ends ofhe md 39. The 'wel engages the swer @ges of thea vmms key .evars 139 sothat Whenevm a@ key i@ dethe Whees sacuixed to h@ jfp Whfse 32.

During the v ,sido 'edges checks to their proper position in thecarriage. A of arms 79 are pivoted on a rod-89 carried by the bent-overedges 65 of the plate Coded springs 8l press the arms 75 toward theplate (S-i to bear upon the paper supported by the carriage and hold thepaper in place. A- cross-bar 82 connects the arms' 79,y the rear 'faceof the bar being serrated to intermesh with teeth on a corresponding bar83 supported by the plate Gl and flush with the front edge thereof.shown in broken lines at 85 in the drawing "is inserted in the carriagethe .arms 7 9 are iirst drawn forwardly and the check dropped into placebetween the arms and the plate The arms are then released and are movedbaclmvardly against the plate by the springs 81 with sufficient force tocause'the teeth on the plate 82 to partially rnutilale the paper againstthe bar 83. 'These teeth are so placed that ythey Will-strike the nameo'f the payee upon the check, thus prevent` ingerasures or alteration ofthe name of the payee. Y 7

The carriage or supporting plate 6-1 is drawn' to the left by a spring9U, 'and its movement under the influence of the spring is controlled byescapement mechanism shown in Fig. 5.' A rack 91 is secured to thecarriage iframe by screws 92, as shown in Figs. 1, 2 and et, and a pairof escape- .ment dogs` 93 and 94 are pivoted -at 95 on an ear 96 securedto one side plate of the bracket 37. lEhe dog 9st is provided with alever arm 97 having a spring 98 secured thereto and attached to a pin 99on the bracket 67. The spring 98 retains the dog 94 against a limit stop10() on the bracket 67. The dog 91 projects beyond its pivot '95 andcarries a .lug 101 for engaging the dog 93. The projecting portion ofthe dog 94 also carries an ear 102, having a spring 103 secured thereto.The opposite end of the s ring 3.63 is attached to an ear 1041 on the og93. This s ring resiliently holds the dog 93 against tiie stop 101. Anactuator arm 195 for the escapement mechanism is pivoted on the shaft 12and has a down- 4Wnrdly and rearwardly pro'ecting arm 106 Aattached tothe shaft 46.

Vhe'n the shaft 46 is moved upwardly by -one of the key levers, the arm105 will press the dog 94 in gagement. The dog 9e will hold the ratchet'bar 91 and the carriage 1n fixed positionv diuring the printingoperation. ."When this 'ldog'is released by the. return movement oflitho arm/195, the spring 98 will Withdraw When. the check or otherpaperl the dog 94 `["rom contact with the ratchet tooth and at the sametime swing the dog 93 into position to engage the next tooth on theratchet(y In this way the carriage is fed one letter space between theprinting operations. Any other suitable escapement mechanism can, ofAcourse, be used for this purpose.
